BACKGROUND Although the measurement site at L4-L5 for visceral adipose tissue (VAT) has been commonly accepted, some researchers suggest that additional upper sites (i.e., L1-L2 and L2-L3) are useful for estimating VAT volume. Therefore, determining the optimum measurement site remains challenging and has become important in determining VAT volume. We(More)
PURPOSE We investigated and identified postmortem changes on magnetic resonance imaging (MRI) of the brain to provide accurate diagnostic guidelines. MATERIALS AND METHODS Our subjects were 16 deceased patients (mean age 57 years) who underwent postmortem computed tomography (CT), MRI, and autopsy, the latter of which showed no abnormalities in the brain.(More)
OBJECT For several decades, clinicians have predicted intraparenchymal brain pressure or brain tissue compression indirectly based on the degree of distortion of the midline structures (midline shift) and ventricle wall (ventriculomegaly) observed on conventional MRI. However, this method has several limitations. Diffusion tensor imaging (DTI) is a novel(More)
PURPOSE Stepping motions have been often used as gait-like patterns in functional magnetic resonance imaging (fMRI) to understand gait control. However, it is still very difficult to stabilize the task-related head motion. Our main purpose is to provide characteristics of the task-related head motion during stepping to develop robust restraints toward fMRI.(More)
This study proposes a novel MRI-powered robotic system controlled with the magnetic field generated by a magnetic resonance imaging (MRI) scanner. In the proposed system, we use an MRI-powered actuator unit proposed in the previous study and a spherical positioning mechanism. The actuator unit contains a ferromagnetic sphere, which acts as a power source(More)
The aim of this study was to compare the effects of low-volume, high-intensity aerobic interval training (HAIT) on maximal oxygen consumption ( $$\dot{V}$$ V ˙ O2max), left ventricular (LV) mass, and heart rate recovery (HRR) with high-volume, moderate-intensity continuous aerobic training (CAT) in sedentary adults. Twenty-four healthy but sedentary male(More)
The fractional anisotropy (FA) is calculated by using diffusion tensor imaging (DTI) with multiple motion probing gradients (MPG). While FA has become a widely used tool to detect moderate changes in water diffusion in brain tissue, the measured value is sensitive to scan parameters (e.g. MPG-direction, signal to noise ratio, etc.). Therefore, it is(More)
Mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) is a clinico-radiological syndrome with a very particular clinical course. Three patients with MERS were evaluated by various sequences of magnetic resonance imaging with diffusion tensor imaging. Initial diffusion-weighted imaging showed reduction in the apparent diffusion(More)
